The crawler plate used in existing crawler crane and other domestic and foreign machinery is casting structure. However, due to the brittleness of the castings and the influence of casting technology and heat treatment, there are many defects in the finished products. It is easy to break the crawler plate in practical application. Because the crawler plate is a casting structure, once cracks or breakage occur, the whole piece of material has to be scrapped and wasted. In addition, the casting track plate needs to be put into mould, heat treatment equipment and so on, and the manufacturing cost is high.

summary of the invention

The purpose of the utility model is to provide f tracked's with respect to the defects existing in the background technology.

The crawler plate can not be scrapped and waste materials, and the manufacturing cost is low.

In order to achieve the above purposes, the technical proposal adopted by the utility model is

A crawler plate of a crawler crane includes a bottom plate, a side rib plate arranged on both sides of the bottom plate, a connecting sleeve fixed on the side rib plate, a connecting sleeve for connecting the two crawler plates, a meshing block arranged at the bottom plate and engaged with the driving wheel, a supporting block arranged on the bottom plate in contact with the supporting wheel of the crawler crane, and a setting thereof. A locating block on the side of the coupling sleeve. The bottom plate, the side rib plate, the connecting sleeve, the meshing block, the support pressing block and the positioning plate are welded to form a welded caterpillar plate.
